From 6600b9dd8e0d4a60c610f216b78d992a598bc52a Mon Sep 17 00:00:00 2001 From: Jiro SEKIBA Date: Mon, 9 Nov 2009 19:10:11 +0900 Subject: nilfs2: move definition of struct nilfs_btree_node This is a trivial patch to expose struct nilfs_fs_btree_node. The struct should be exposed outside of kernel, for it is disk format.
